Description

Odor gas removal device {DOROUS GAS TREATMENT APPARATUS}

The present invention relates to a malodorous gas removal device, and relates to a malodorous gas removal device that removes odor from a place where odor is generated, such as a barn.

In general, in livestock breeding places such as pig houses, cages, or barns (hereinafter referred to as "livestock"), if the treatment of livestock excreta or waste is not performed in a timely manner, Odor is generated by gases such as hydrogen sulfide, ammonia, methyl mercaptan, methyl sulfide, methyl disulfide, amines, and acetaldehyde generated from the excrement.

When such odor is inhaled into the respiratory tract of livestock for a long time, it causes death of livestock, and causes stress to livestock, resulting in problems in growth and pregnancy of livestock.

Therefore, an operation capable of removing odors by deodorizing odorous gases such as ammonia, methyl mercaptan, hydrogen sulfide, etc., which cause odors, is required before a gas above a certain level is generated.

On the other hand, according to the Odor Prevention Act (Ministry of Environment), which came into effect in February 2005, from January 1, 2006, regulations on the emission of designated odorous substances such as ammonia and hydrogen sulfide have been implemented for livestock facilities with an area of more than 50㎡ for pig breeding facilities. It is becoming.

In order to satisfy such an odor prevention method, a method for effectively removing odorous substances present in the air in a pig house is urgently required.

On the other hand, since the barn, such as a pig house, has a strong odor, it is difficult to install air conditioning facilities such as air conditioners or hot air fans therein. That is, when an air conditioning facility is installed inside the barn, it is difficult to install the air conditioning facility in the pig house because odorous components such as hydrogen sulfide and ammonia corrode the internal components constituting the air conditioning facility and cause a breakdown after not using it for a while.

However, if the temperature inside the pig house exceeds 40 ℃ in summer, the pigs die, so it is necessary to adjust the temperature inside the barn according to the season.

In the present invention, the barn 10 has been described as an example, but it can be applied to various other places where odors occur.

As shown in FIG. 1, in the barn 10, a manure discharge plate 11 is provided at the bottom of a space where livestock are raised, and a manure discharge tank 13 is provided at the bottom. The manure in the manure discharge tank 13 is discharged into the manure storage tank 15.

The odorous gas (A) containing odors such as manure and dirt is introduced into the odorous gas removal device 100 through the odorous gas inlet pipe 111 connected to the wall of the barn, and the odorous gas removal device 100 removes odorous components The odor removal air (A7), which has been removed and the temperature is controlled, is re-introduced into the barn 10 through the odor removal air circulation pipe 115. As a result, the concentration of odorous components inside the barn 10 can be adjusted and the internal temperature can be adjusted.

As shown in FIG. 2 , the malodorous gas removal device 100 includes a casing 110 in which a malodorous gas inlet pipe 111 and a malodor removing air discharge pipe 113 are coupled, and a malodorous gas inlet pipe 111 of the casing 110. ) side to remove the dust components of the odorous gas (A) by spraying water (W); A wet malodor removal unit 130 that sprays water and brings the malodorous gas (A) into contact with the first cooler 133 and the heater 138 to remove odor components by condensation, and a wet malodor removal unit 130 A temperature control unit 140 provided at the rear end of the tertiary process air (A3) to control the temperature of the tertiary process air (A3), a primary water removal space 150 for removing moisture contained in the 5 tertiary process air (A5), and a secondary The moisture removal space 160, the air blowing space 170 for discharging the odor removal air A7 passing through the secondary moisture removal space 160 to the odor removal air discharge pipe 113, and the wastewater in which odor components have been cleaned It includes a water circulation unit 180 for circulating water (W) by mixing the neutralizing agent.

In the casing 110, the odorous gas (A) introduced into the interior is sequentially passed through the dust shower unit 120, the wet odor removal unit 130, the temperature control unit 140, the primary moisture removal space 150, and the secondary After passing through the water removal space 160 and the blowing space 170, each component is supported so that odor components can be discharged in a removed state.

The casing 110 may be disposed outside the barn 10 or inside the barn 10 as shown in FIG. 1 .

One end of the casing 110 is provided with a stinking gas inlet pipe 111 connected to the barn 10 and introducing the stinking gas A inside the barn 10 to the dust shower unit 120. At the other end of the casing 110, an odor removal air discharge pipe 113 is provided to communicate with the blowing space 170 and discharge odor removal air A7 from which odor components are removed.

The odor removal air discharge pipe 113 is connected to the odor removal air circulation pipe 115 for resupplying the odor removal air A7 to the barn 10. A discharge path control valve 117 is provided in the branching area of the odor removal air discharge pipe 113 and the odor removal air circulation pipe 115 to control the discharge air of the odor removal air.

The dust shower space 121, the wet odor removal unit 130, the temperature control unit 140, the primary moisture removal space 150, the secondary moisture removal space 160, and the blowing space 170 are arranged adjacent to each other It is provided in an open state to each other so that the processing air can proceed sequentially.

By the blowing pressure of the blowing fan provided in the odor gas inlet pipe 111, the odor gas (A) sequentially moves toward the odor removal air discharge pipe 113 without going backwards inside the casing 110.

On the other hand, in the lower part of the casing 110, the wastewater W1 and condensate E falling from the dust shower unit 120, the wet odor removal unit 130, and the temperature control unit 140 are mixed with water in the water circulation unit 180. A water discharge plate 119 for discharging water into the tank 181 is provided.

The dust shower unit 120 sprays water (W) to the odorous gas (A) introduced into the inside through the odorous gas inlet pipe (111) to dissolve and remove water-soluble odorous components included in the odorous gas (A). As shown in FIG. 3, the dust shower unit 120 includes a dust shower space 121, a plurality of first shower nozzles 123 provided above the dust shower space 121 to spray water W, It includes a plurality of mist nozzles 122 provided around the first shower nozzle 123.

The first shower nozzle 123 sprays water W at low speed and low pressure to wash away the dust B included in the odor gas A moving toward the wet odor removal unit 130 . Wastewater (W′) in which dust is dissolved is dropped into the water discharge plate 119 and stored in the water tank 181.

4 is a diagram showing the operation process of the dust shower unit 120. As shown in an enlarged view, the odorous gas (A) flowing into the odorous gas inlet pipe 111 includes dust (B) of relatively large particles, wet steam (F), and odorous components (S) of small particles.

The dust shower unit 120 removes the dust (B) contained in the odorous gas (A) by washing it with water, and causes the wet steam (F) to condense and fall downward. Then, the mist (M) is sprayed so that the mist (M) is combined with the odor component (S) so that the odor component (S) is moved to the neighboring wet odor removal unit (130).

Since the water molecules sprayed from the first shower nozzle 123 are large, the dust (B) with large particles is separated from the odorous gas (A) by the spray pressure of the water and is washed with the water (W) to move to the lower part. do. In addition, the wet steam (F) is condensed by the temperature difference of water and moved to the lower part.

The mist M has fine particles and is sprayed from the mist nozzle 122, and then floats and stays in the dust shower space 121. In this process, the mist (M) penetrates between the small-sized odor components and is combined with the odor component (S).

Since the mist (M) surrounding the odor component (S) is light, it moves to the wet odor removal unit (130). Accordingly, the dust shower unit 120 can intensively remove only the dust (B) included in the odorous gas (A).

On the other hand, the mist nozzle 122 may selectively inject cold mist M or high-temperature steam according to the type of odor generating place and the temperature of the malodorous gas A. The mist nozzle 122 receives and sprays the mist by the mist supply unit 122a.

The mist supply unit 122a may generate mist by ultrasonic waves or boil water to generate high-temperature mist, that is, steam. The mist supply unit 122a supplies mist or steam to the mist nozzle 122 according to the temperature of the odorous gas A.

The wet odor removal unit 130 contacts the water W and removes odor components from the dust-removed primary treated air A1. As shown in FIG. 2, the wet odor removal unit 130 includes a cooling shower space 131 in which a plurality of first coolers 133 in which the refrigerant C is moved are arranged in a zigzag shape in the height direction, and a cooling shower space A heat shower space 137 equipped with a heat generator 138 disposed adjacent to the 131 and in contact with the primary processed air (A1) in the first cooler 133 and moving the refrigerant (C) whose temperature has risen include

At the top of the cooling shower space 131 and the heat shower space 137, a second shower nozzle 135 and a third shower nozzle 139 spraying water (W) to the first cooler 133 and the heat generator 138, respectively. ) is provided. The water (W) sprayed from the second shower nozzle 135 and the third shower nozzle 139 covers the surfaces of the first cooler 133 and the heat generator 138 as shown enlarged in FIG. The surfaces of the first cooler 133 and the heater 138 are prevented from being corroded by odor components remaining in (A1).

The first cooler 133 and the heat generator 138 are connected to each other through a cooling cycle so that the refrigerant C is circulated. In this process, the surface of the first cooler 133 is coldly cooled, and the surface of the heater 138 remains hot.

When the primary processed gas (A1) flows into the cooling shower space 131 and contacts the first cooler 133, the temperature (T2) of the primary processed gas (A1) is higher than that of the first cooler 133. 1 Condensation occurs on the surface of the cooler 133. Odor components are dissolved in the generated condensate (E) and fall together to the lower portion, and the odor components are removed.

The secondary processed air (A2), which is in contact with the first cooler 133 and whose temperature is lowered, moves to the heated shower space 137 and then comes into contact with the heater 138. Since the temperature of the heat generator 138 is higher than the temperature (T3) of the secondary treated air (A2), the secondary treated air (A2) is in contact with the heat generator 138 and the water (W) absorbed in the dust shower space 121 it evaporates In this process, the humidity of the tertiary treated air (A3) is lowered.

The temperature controller 140 controls the temperature of the tertiary treatment air A3 whose humidity has been lowered through the heat shower space 137 . The temperature control unit 140 cools the tertiary processed air (A3) so that cold air having a temperature lower than room temperature is supplied to the barn 10 in summer, and warm air having a temperature higher than room temperature is supplied to the barn 10 in winter. let it be In addition, in spring and autumn, the temperature of the odor removal air A7 is adjusted to a temperature corresponding to room temperature.

As shown in FIG. 5, the temperature controller 140 has a cooling space 141 for lowering the temperature of the tertiary processing air A3 whose temperature has increased in the heat shower space 137, and a temperature in the cooling space 141. It includes an internal heating space 147 through which the lowered 4th process air A4 passes, and an external heater casing 145 provided outside the casing 110 .

The second cooler 143 through which the refrigerant flows is accommodated in the cooling space 141, and the internal heater 148 and the external heater 146 are accommodated in the internal heating space 147 and the external heater casing 145, respectively.

Here, the second cooler 143 is selectively connected to the internal heater 148 or the external heater 146 depending on the season. That is, in the season when the inside of the barn needs cooling, the second cooler 143 is connected to the external heater 146, and in the season when the inside of the barn needs heating, the second cooler 143 is connected to the internal heater 148.

In summer, when the temperature (T1) inside the barn is high, the tertiary processed air (A3) in the cooling space (141) contacts the second cooler (143) and the temperature is lowered (T5 < T4). In this process, condensed water (E) generated in contact with the second cooler 143 descends to the floor.

The 4th process air (A4) whose temperature has decreased is moved to the internal heating space (147). At this time, when the internal heater 148 is operated, the temperature of the 4th process air A4 increases again. Accordingly, in the summer season, the refrigerant path control valve 144b is opened and closed so that the refrigerant of the second cooler 143 is circulated by the external heater 146 of the external heater casing 145 and the external refrigerant circulation pipes 144 and 144a.

Since the refrigerant is not circulated in the internal heater 148, the temperature T6 of the 5th processed air A5 passing through the internal heating space 147 becomes the same as the temperature T5 of the 4th processed air A4. Then, the temperature (T5) cooled in the cooling space 141 is maintained thereafter to cool the inside of the barn (T1>T5).

On the other hand, when the temperature (T1) inside the barn is low in winter, the internal heater 148 is operated so that the refrigerant circulates through the internal heater 148. As a result, the temperature of the tertiary processed air A4, which is lowered in contact with the second cooler 143 in the cooling space 141, comes in contact with the internal heater 148 and is increased in temperature. Accordingly, the temperature T6 of the fifth treated air A5 is higher than the temperature T5 of the fourth treated air A4 and higher than the indoor temperature T1 of the barn.

Also, in this process, the 5th process air A5 has a lower humidity after being in contact with the internal heater 148 .

The primary moisture removing space 150 is filled with a moisture removing agent 151 therein to remove moisture contained in the 5th processed air A5.

The secondary moisture removal space 160 removes moisture contained in the 6th processed air A6 from which moisture is first removed in the primary moisture removal space 150 again. The secondary moisture removal space 160 removes moisture using the eliminator 161 .

As shown enlarged in the lower part of FIG. 5, a plurality of eliminators 161 are arranged at narrow intervals along the height direction in the secondary water removal space 160, and 6th treatment is performed between neighboring eliminators 161. Air (A6) is moved.

At this time, the eliminator 161 is provided in a curved shape and has a break point 161a at which an inclined direction is changed. The sixth treated air (A6) comes into contact with the inclined surface of the eliminator 161 and condensation occurs, and the condensed water moves along the inclined surface and then moves downward at the break point 161a.

The blowing space 170 accommodates a plurality of blowing fans 171 therein, and communicates with the odor removing air discharge pipe 113 of the casing 110. The blowing space 170 blows the odor removing air A7 passing through the secondary moisture removing space 160 to the odor removing air discharge pipe 113 using a blowing fan 171 .

At this time, according to the operating direction of the discharge path control valve 117 coupled to the odor removal air discharge pipe 113, the odor removal air (A7) is discharged into the atmosphere or ) is re-supplied.

The water circulation unit 180 allows water used for cleaning the odorous gas A to be circulated inside the casing 110 . As shown in FIG. 3, the water circulation unit 180 is provided in the lower portion of the casing 110 and includes a water tank 181 in which the wastewater W' is accommodated, and a water nozzle accommodated in the water tank 181 to discharge the wastewater. (123, 135, 139), the water supply pipe 185, the water tank 181 discharges the waste water (W') to the water supply pipe 185, the water pump 183, and the water supply pipe 185 to the waste water (W') ) And a neutralizing agent metering pump 189 for supplying a neutralizing agent for neutralizing.

The neutralizing agent metering pump 189 supplies the neutralizing agent from the neutralizing agent storage tank 187 to the water supply pipe 185.

As a result, water (W) diluted with the neutralizer (D) to neutralize odor components is supplied to the dust shower space 121 and the wet odor removal unit 130 through the shower nozzles 123, 135, and 139, and the odor gas (A) The waste water (W′) used for cleaning is discharged to the water tank (181).

Then, the wastewater (W') goes through a circulation process in which it is mixed with the neutralizer (D) and supplied to the shower nozzles (123, 135, 139).

Here, a water outlet 181a for discharging wastewater W' to the outside and a discharge cap 182 for opening and closing the water outlet 181a are provided on the bottom surface of the water tank 181 .

If the circulation of the wastewater (W') is repeated, odor components that are not neutralized even by the neutralizing agent (D) may exist. Therefore, it is preferable to discharge the wastewater (W') at regular intervals and use new water.

An odor removal process using the odor gas removal device 100 of the present invention having such a configuration will be described with reference to FIGS. 1 to 5 .

The odor gas removal device 100 may be selectively provided outside or inside the barn 10. The odor gas inlet pipe 111 of the casing 110 is connected to one end of the barn 10 and the odor removal air circulation pipe 115 is connected to the other end of the barn 10.

When a blowing fan (not shown) provided in the odor gas inlet pipe 111 is operated, the odor gas A inside the barn 10 flows along the odor gas inlet pipe 111 to the dust shower space 121 of the casing 110. ) is introduced into The odorous gas (A) introduced into the dust shower space 121 comes into contact with the water (W), and dust components with large particles are washed away. Then, the mist (M) sprayed from the mist nozzle 122 surrounds the odor component (S) contained in the odor gas (A) and moves to the cooling shower space (131).

The primary processed air (A1) from which dust is removed from the dust shower space 121 is moved to the neighboring cooling shower space 131 and comes into contact with the first cooler 133. The primary processed air (A1) in contact with the first cooler (133) is condensed on the surface of the first cooler (133) due to the temperature difference, and the condensate (E) in which odorous components are dissolved falls to the bottom of the casing (110).

The secondary processed air (A2) from which odor components are secondarily removed in this way contacts the heater 138 in the heated shower space 137, and moisture is evaporated to lower the humidity and increase the temperature again. The tertiary processed air (A3) passing through the heat shower space 137 is moved to the cooling space 141 of the temperature control unit 140, then comes into contact with the second cooler 143, and the temperature T5 is lowered again.

The 4th process air A4 cooled in the cooling space 141 is moved to the internal heating space 147 . The internal heater 148 provided in the internal heating space 147 operates only during the winter season and is not operated during the other seasons.
